SPECIFICATION forming part of Letters Patent No. 529,031, dated November13,1894. Application tiled June 4, 1894. Serial No. 513,402. (No model.)

To @ZZ whom t may concern.-

13e it known that I, LUTHER M. JOHNSON, a citizen of the United Statesof America', residing at Paulding, in the county of Pauldlng and Stateof Ohio,-have invented certain new and useful Improvements in Elevators,of which the following is a specification, reference being hadtherein tothe accompanying drawings. Y

My invention relates to improvements in elevators, which while it may beused for any p urpose for which it would operate, is speciallyconstructed for elevating cakes or blocks of ice and depositing them inrefrigerators or cold storage receptacles, and the f object of myinvention is the provision of a portable elevator which will be easy tooperate and which will quickly elevate and deliver or deposit the blocksof ice and which will be of the simplest, cheapest and most durableconstruction and thus produce a thoroughly practical elevator. g

The invention consists of an ice elevator embodying novel features ofconstruction and combination of parts substantially as disclosed herein.

Figure 1 represents a perspective View of my improved elevator. Fig. 2represents a vertical sectional view of the elevator with the parts inthe position they assume before delivering the block of ice, and Fig. 3represents a similar view With the parts in the position they occupywhen the block of ice is being delivered or deposited. Fig. 4 representsa detail view to particularly show the coiled spring and its relation toadjacent parts. v

In the drawings, the letter A designates the base of my elevator fromwhich rise the vertical standards B, having on the inner faces thegrooves, channels or guide ways C, and the top connecting or cross pieceD, the whole structure forming a strong and durable frame work buteasily transported from place to place vwhen desired.

Fitting in the guide ways is the rectangular open traveling frame E,carrying at the top the grooved pulleys F,which are in line with the4grooved pulleys G, secured or mounted in bearings on the top piece ofthe frame and over these grooved pulleys pass the cords, ropes or chainsH, having their lower ends connected to and adapted to be wound upon thewindlass or drum J, mounted in bearings K secured Yto the frame, and onthe drum shaft is a crank L, for rotating the windlass to cause thetraveling frame to be moved up or down in the guide ways, and to holdthe traveling frame at any desired point I place on the drum the ratchetwheel M, with which engages the dog or detent N, mounted in a suitablebearing on the frame and having thelever O, for engaging or dsengagingthe detent as circumstances require. l

In the traveling frame is secured a crosspiece P, to which is rigidlysecured the inclined ice supporting platform Q, which is suitably bracedand retained against all strain, and adjacent to the cross piece isarranged bearings R, in which is secured arod S, on which is mounted thetilting platform T, and around the rod is coiled a spring U, which hasthe free ends bearing against the cross piece and a stud or lug U',secured to the tilting platform, and. the spring acts to throw theplatform down or tilt the same to discharge the i'ce, and the limitingbale V, is provided to limit the movement ofthe platform when itdescends to discharge the ice.

From .this construction it will be seen that the coil of the spring isarranged on the rod and one end is held rigid against the crosspiece andthe other end which is free exerts its tension downward against the studU', and pushes the tilting platform down when released.

To the free edge of the tilting platform is secured the keeper plate YV,adapted when the platform is lifted, either by raising it up with thehand or by using the lifting cord X, to engage the latch Y, having thespring Y', for controllingor holding the latch and to hold the platformin the position shown in Fig. 2, and when the platform is raised, byturning the drum through the medium of the cords connected with theframe and drum, the end of the pivoted latch Y, is struck against thestop Z, which is secured to the top piece of the frame, and the stopdisengages the latch from the keeper on the tiltroo the block of icefrom the rigid inclined plat.

form slides upon the tilting platform and from thence to the ice box, asis evident. The stop plate Z, is provided with a slot Z by means ofwhich the plate can be adjusted to cause it to engage the latchatdifferent adjustments.

1. In an elevator, the combination of the vertical frame having theguideways, the frame fitting in said guideways, the rigid inclinedplatform secured to the frame, the rod secured in the frame adjacent tothe rigid platform, the tilting platform hinged-to said rod, the springcoiled around the rod and having one end bearing against the frame andthe other end bearing against the tilting platform, the keeper securedto the tilting platform, the latch for holding the keeper, the stop forengaging the latch to release the same and allow the platform to falland mechanism for moving the frame.

2. In an elevator, the combination of a base, the vertical uprightsrising therefrom and having guideways, the drum mounted in the u prights and having the ratchet, the dog engaging the ratchet and having ahandle, the cords on the drum, the traveling frame connected to thecords, the rigid and hinged 3o platforms carried by the traveling frame,the keeper and latch for securing the hinged platform, the stop forengaging the latch to allow the hinged platform to descend and the baleon the vertical uprights for limiting the 35 descent of said platform.

In testimony whereof Iafix my signature in presence of two witnesses.
